Cover Story: Automotive three-way catalysts (TWCs) reduce toxic emissions but need replacing after 8–10 years of use, resulting in substantial amounts of palladium-rich waste. Current pyrometallurgical routes to recycle this precious metal content are very energy-intensive and require the use of hazardous chemicals. More recently, a mild, low-energy process has been reported that can transform model TWC material into the palladium dimer [NnBu4]2[Pd2I6] in high yields and purity. In this contribution, we demonstrate that this dimeric recovery product, and its derivative PdI2(dppf), can be employed as effective (pre)catalysts for the formation of new C-O and C-N bonds in low-impact solvents. [NnBu4]2[Pd2I6] can also be recovered and re-used multiple times after the reaction, providing additional sustainability benefits. View this paper
